Why lose time to register and post you're going to try it, instead of just trying it and then posting if you still have problems? Anyway, if you tried it, you should have the game installed and patched; then you just need to point Residual to the install dir, which is straightforward and self-explanatory once you run Residual.

Edit: An officially stable release of ResidualVM is out since 2012/12/21. Regardless of whether the game is patched or not, the new Residual version refuses to launch the game unless the patch installer (gfupd101.exe) is placed in the install dir.
